Technical analysis and application exploration of SPDU

Short-range distillation, as an efficient liquid-liquid separation technology, has been widely used in many fields such as chemistry, pharmaceutical, food and environmental protection in recent years. Its core component, the short-range distillation element, is the key to achieving efficient separation. In this paper, the structure, working principle, performance characteristics, application field and future development trend of short-range distillation elements will be deeply discussed, in order to provide valuable reference for related industries.

The short-range distillation element usually consists of heating system, evaporation surface, condenser, collection system and control system. Its core is to use the volatility difference between molecules to achieve rapid vaporization and condensation in a high vacuum environment, so as to achieve the purpose of separating the mixture.

► Heating system: Responsible for heating the mixture to the desired evaporation temperature. The heating system is usually electric heating or steam heating, which can precisely control the heating temperature to ensure the stability of the evaporation process.

► Evaporation surface: It is the main place where the mixture evaporates. The evaporation surface is usually made of special materials with good thermal conductivity and corrosion resistance. During evaporation, the liquid molecules in the mixture form steam on the evaporation surface and diffuse towards the condenser.

► Condenser: Located on the opposite side of the evaporation surface, it is responsible for condensing the steam into a liquid. The condenser usually uses an efficient cooling system inside, which can quickly reduce the temperature of the steam, so that it condenses into a liquid. At the same time, the structural design inside the condenser is also crucial to ensure that the steam can be evenly and quickly condensed.

► Collection system: Responsible for the collection of condensed liquid. The collection system is usually connected to the condenser to ensure that the condensate is collected in a timely and complete manner.

► Control system: responsible for accurate control of heating temperature, vacuum degree, flow rate and other key parameters. The control system usually adopts advanced digital technology, which can realize automatic control and remote monitoring, improve operational efficiency and safety.
